I am trying to explain why the voltage increases when the frequency increases. I am testing a piezoplate at 1Hz and 2Hz, 10 cycles and a force of 30N. I collect the voltage difference. The votlage increases with frequency.
The equations for piezoelectricity are:
ε = SE * σ da 33* Efield
Electric Displacement = d33a * σ + (Permitivity) * Efield {Eq. 4}
So.....what parameter depends on frequency? Is it the permitivity?
